Google Sheets script to ignore or include specific sheets - google-sheets

Question

I am getting this error: TypeError: Cannot call method "getName" of null. I have used a script to replace the formulas of the active sheet with the cell values. However, I don't want to accidentally run this on a few sheets, so I want to be able to exclude or include only specific sheets. I have been following another post and came up with this, and now I have the error:
function freezeValues() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheets = ss.getSheets();
//loop through all sheets and get name to see if it includes specific string
for (i = 0; i < sheets.length; i++) {
var sheet = ss.getSheetByName(sheets[i]);
var name = sheet.getName();
if (name.includes("String_00")) {
//get active sheet and replace range with values
var sheetActive = ss.getActiveSheet();
var range = sheetActive.getRange("A1:Z50");
range.copyTo(range, {contentsOnly: true});
} else {
continue;
//skip over all those that don't meet the condition
}
}
}
UPDATE:
Trying this:
function freezeValues() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheets = ss.getSheets();
//loop through all sheets and get name to see if it includes specific string
for (i = 0; i < sheets.length; i++) {
//var sheet = ss.getSheetByName(sheets[i]);
var name = sheets[i].getName().toString();
if (name.indexOf("String_00") > -1) {
//get active sheet and replace range with values
//var sheetActive = ss.getActiveSheet();
var range = sheets.getRange("A1:Z50");
range.copyTo(range, {contentsOnly: true});
} else {
continue;
//skip over all those that don't meet the condition
}
}
}
But now it doesn't do anything. using .include was giving me an error, so I moved over to .indexOf() > -1. Does not freeze data as expected for any sheet, regardless of name.

Answer 1

I came up with 2 solutions for this, sort of started from the drawing board. One creates an array, a sort of blacklist, and then if the sheet name contains any item in the blacklist, then it returns and doesn't execute the replacement. The second solution searches for a pattern in the sheet name and only then continues on to the replacement. Both accomplish what I was trying to do. I think the code I found was a bit buggy and was a bit complicated for what I was doing. I didn't need to loop through all sheet names, just check the sheet name against given variables. Anyway, here they are:
This one creates the array blacklist of pages not to edit:
function freezeValues() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheets = ['Sheet1', 'Sheet2', 'Sheet3', 'Sheet4'];
var sheetActive = ss.getActiveSheet();
if (sheets.indexOf(sheetActive.getName()) > -1) return;
var range = sheetActive.getRange("A1:Z50");
range.copyTo(range, {contentsOnly: true});
}
This one only searches for specific text in the sheet name before proceeding with the replacement.
function freezeValues() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheetActive = ss.getActiveSheet();
var name = sheetActive.getName()
if (name.indexOf("String_00") > -1) {
var range = sheetActive.getRange("A1:Z50");
range.copyTo(range, {contentsOnly: true});
}
}
I'm sure there is a method to use sheet index value so if you want to skip the first 4 sheets, you can probably do that as well, so it doesn't call on names at all.
UPDATE
function freezeValues2() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheetActive = ss.getActiveSheet();
if (sheetActive.getIndex() > 4) {
var range = sheetActive.getRange("A1:Z50");
range.copyTo(range, {contentsOnly: true});
}
}
